I! 2) MM ii /Loni it may concern:

Be it known that I, Onannns K. BUL- UARLDES, a citizen of the United States, residing at Tacoma, in the county of Pierce and ritate o't lVashington, have invented certain new and useful improvements in Gallring- .lrll achines, oil? Which the :liollowing is a specilieation.

The present invention coinprehends genen ally improvements in that class of inventions known as ships and more particularly relates to a calliing inachine.

'llhis invention has for its principal object to provide a machine oi the above mentioned. character designed for calking the spaces between adjacent planks, forming the decking ot a ship, or other surface, the component partsbeing oi novel constructioi'i to cooperate with each other in such a manner that when the calhing material is being ted, desi rahly. in the form of a string, .it is bunched or i'olded in much the same manner as it ted by hand and is subsequently effectively rallied in position.

llllore particularly, this invention contemplates the provision of a machine of the above mentioned characti-n' wherein there is provided plunging or calking means and 'leeding' means, iin iroved actuating means being arranged in connection With the planning means for moving the :lieedinn' means in one direction while acting in conjunction nfith the feeding; means is improved resilient means tor insuring; 01. the bunchingr and Folding: of the calking material so that it will be immediately and subsequently acted upon by the planning means and properly arranged in position. K

its an addition a]. object, the invention enilmeees the provision of a machine of the aboven'ientioned character wherein main. and secondary frames are provided, the main frame being adjustable so as to vary the distance between the main frame and the dechinp; While resilient means are interposed between the main and secondary frames for vieldinn'lysupporting the secondary frame. and this resilient means in addition acts as a shock absorber for the plunging means.

A still further object of this invention is to provide a machine of the above mention ed character wherein the feeding; means is of novel construction and is adjustabl sun ported from the secon5a.]? frame and positioned beneath. the main tfra me as Well as the plunging; means and the said teedinp; means is incidentally designed so that it may be locked in an inactive position Without intertlering with the independent operation of the plunging means, should it be desired to use the machine in such manner.

More specific objects of this invention may be said to consist in the provision of a machine of the above mentioned character wherein guides are en'iployed for engagement with the groove or space between the planks forming the decking for consequently keeping the machine in the proper position as it is being moved :lorivardly and operated; to provide feeding means wherein the guid- .lllg or bunching means and the feeding finger are of novel construction; to improve the cinistruction oi the shoes of the feeding means so that they will etlcctively insure of the movement of the feeding means in one direction when engaged by the reciprocating actuators or operating arms; and to also provide improved means for mounting and actuating the callcingr tool and the actuating arms.

Among; the other aims and objects of the present invention may be recited the pro vision of a machine of the above mentioned elnurac-ter, comparatively simple in construction. durable, and one Which will be very ellieient and i'lse'l ul in operation.

With the above and other objects in view. the invention accordingly consists in the novel features oi construction, combination and arrangement of parts as will be hereinaitter referred to and more particularly pointed, out in the, specification and claims.

The invention is clearly illustrated in the. accom ninyinn drawings, in Which:-

Similar characters of reference are employed in all of the above described views, to indicate corresponding parts.

' Referring now, more particularly, to the accompanying drawings there is provided a main frame preferably of a rectangular configuration consisting of side bars 1 connected by a front cross bar 2 and a rear cross bar 3. Arranged between the rear portion of the frame are bearing plates t in which is journaledan axle 5 having supporting rollers or wheels 6 mounted thereon while elongated bolts 7 are adjustably arranged through the respective ends of these bearing plates and through the adjacent side bars 1 and the rear cross bar 3 being in turn engaged by nuts which cooperate with the plates and the side and end bars for adjustably mounting the rear portion of the frame with respect to the deck 9. In supporting the front end of the frame spaced bearing blocks 10 are adjustably mounted on the front cross bar 2 being rigidly held at various adjusted positions by means of set screws 11. These blocks 10 are formed with vertical bores in which are mounted the threaded portions 12 of supporting legs 13 to the lower ends of which arerigidly fastened brackets 1% while supporting rollers 15 are j ournaled in these brackets and are of course engageable with said deck 9. Suitable adjusting elements such as nuts 16 are mounted on the threaded portions 12 of the legs and act as bearings contacting with the upper and lower edges of the bearing block 10 for insuring of the maintenance of the legs in the properly adjusted positions. By this construction it is apparent that the forward portion of the frame is adjusted with respect to the deck.

As intimated, there has been provided a secondary frame generally indicated by the numeral 16. In reducing this feature of the invention to practice the frame may be said to consist of a pair of substantially U-shaped supports comprising an intermediate portion which constitutes a cross bar 1'7 and spaced standards 18 while bracket arms 19 project outwardly at right angles preferably from the upper and lower ends of these standards. A platform 20 is supported upon and secured to the cross bar 17. Opposed pairs of vertical rods 21 rise from the side bars 1 of the main frame near the ends thereof and are engaged by thebrackets 19 while disposed about these rods and positioned respectively between the side bars 1 and the lower brackets and between the upper brackets and adjustable elements such as nuts 22 mounted on the upper ends of the rods 21. are coiled springs and 24. These springs serve to yieldably support the secondary frame with respect to the main frame and in addition serve as a means for absorbing shocks likely to be transmitted to the calking chisel in a manner that will hereinafter become apparent.

With a view toward providing the improved plunging or calking means proper a standard 25 is mounted on the platform. 20 while also mounted on the platform directly in advance of the standard is a casing 26 desirably of a rectangular configuration the side walls of which are formed with opposed slots 27 while the front wall is provided with spaced vertical slots 28 for a purpose that will presently appear. A shaft 29 is retatably mounted in the upper end of the standard 25 while carried by one end of the shaft and positioned within the casing 26 is a disk 30. A pin 31 extends eccentrically from the outer face of the disk and is formed with a head 32. This headed pin is arranged in engagement with a correspoint ingly formed transverse or diametrical slot 33 provided in the adjacent face of another disk 34. A plunger rod 35 is secured by suitable fasteners 36 vertically of the opposite face of the disk 34: and is slidably ::r-- ranged through opposed openings in the top of the casing 26 and in the platform 20. By this construction it will be up parent that when the shaft 29 is rotated owing to the pin and slot connection between the disks 30 and 34c and the slidablc mounting of the plunger rod the latter will be reciprocated during the rotation of the shaft 29. A chuck head 37 is formed on the lower end of the plunger rod 35 and receives the calking tool generally designated by the numeral 38 in the present instance in the form of a chisel having a shank 39 formed on its upper end with a head 40 which is receivable in the chuck while the outer edge of the engaging end of this chisel is curved longitudinally as at 41. and transversely as at 42 this construction serving to insure of an effective tamping or calking of the milk-- ing material. in. a manner that will hereinafter become apparent. A counterbalancing weight in the form of a ball 4-3 is detachably connected to the upper projecting end of the plunger rod iictnatable with the plunger rod and positioned forwardly of the casing and vertically slidable through openings in the platform 20 are spaced :ictuator arms 43 for the feeder mechanism. Connection is preferably maintained bctween these arms 'by means of bracket arms 4A the outer ends of which are detachably fastened by suitable fasteners such as screws 4C5 to the upper ends of the arms while the inner ends are fastened as at 4-6 to the rod 35, the medial portions being slidable through Cir lllt) order that the plunging or calking means may be. operated independently of the feeding and bunching means, it is only necessary toeengag'e the plate 72 and-move it forwaidly so that it may be engaged with the lugs 81 on therod and thereby locked in afterward orinactive position.

Coiiperating with the groove engaging guides. 67 and 68 is another guide 90, the threaded shank 91 of which is arranged through a-bearing block 92 in turn adjustably mounted on theirear cross bar 3. A set-screw 93 serves to maintain the bearing block 92 in position while suitable adjust 'able elemen ts such as nuts 94 are mounted on the threaded shank 91 to cooperate with the block 92 and maintain the shank 91. of theguide: in a properly adjusted position relative to the decking. A bracket is preferably connected to the shank 91 of the g'uideOO while journaled in this bracket is a supporting roller 96 for insuring of a proper actuation ofthe guide and maintaining. it in a-properposition -within the" groove .69.

To facilitate the manipulation of the mach-ine, gripping handles 97"are connected to the top of'thecasing 26 and the reariU- shaped support-of the secondary frame.

I The mode-of operation of the present invention maybe reviewed as follows:

P Assuming that the parts"have..been assembled in the manner described and as illus trated in the drawings'when the motor i8 is started. rotary motion will be transmitted thereby to the shaft 29 tdrotate the disk 30 and. by reason of the eccentric connection of the headed pin 31 and its'sliding engagement inthe slot 33, the disk 34 will be recip- :roc'a'ted T to consequently reciprocate the plunger'in'a vertical direction and thereby insure/of a properreciprocation of the calking chisel 39 as well as the actuator arms 43- which' arelconnected to the plunger rods rods 71 and shoes-82' rearwardly, the finger 84:- wliich-is movable with the shoes of course,drawing a new bunch of'calking ma- "terial and forcing it through the guides 89 so astobunch or fold the material in much the same manneras if done by hand, the

guides positioning the bunched material directly benea'ththe 'calkingchisel 38 so that when thelatterj moves downwardly on its next stroke the bunched material will be forced through the space between the sides of'theframe 61 into'the groove 69 to ulti mate'ly insure of a an "efi'ectivejcalking of this groove or-spacebetween the planks forming the decking 9. During the operation of these parts the machine of course is being moved forwardly over the deck and is guided inits movement by the guides ('37, 68 and 90 which insure of the working parts being arranged. over the groove 69 at all times. In connection with the foregoing, it is to b understood that the springs 23 and 24; which yieldably support the secondary frame also act as recoil springs taking shock of the chisel 3S oii' of the machine. To permit of the independent operation of the calking chisel it is only necessary to arrange the plate 72 in a forwardly locked position behind the lugs 81 thus locking the feeding mechanism in inactive position. This is done at times when the first piece of material is laid in the groove (39.

It is believed in view of the foregoing description that a further detailed description of the operation of the invention is entirely unnecessary. Likewise it is believed that the As many changes could be made in the above construction and many apparently widely different embodiments of this invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
